Information storage and retrieval
First Claim
1. An information retrieval system in which a set of distinct information items map to respective nodes in a self-organizing map by mutual similarity of the information items, so that similar information items map to nodes at similar positions in the self-organizing map, wherein the self-organizing map is trained upon reduced dimension characterizations of the information items, the system comprising:
- a user control configured to define a search criterion for selecting a subset of the information items represented by the self-organizing map, the search criterion being applied using a standard keyword search technique;
a detector configured to detect those positions within the self-organizing map corresponding to the subset of the information items selected by the standard keyword search technique;
a graphical user interface configured to display points representing only those positions within the self-organizing map corresponding to the selected subset of information items; and
a processor, responsive to the selected subset of information items selected using the search criterion, configured to provide one or more representations representative of the information content of the selected subset of information items,wherein each of the information items represented by the self-organizing map includes image data; and
wherein the processor is responsive to the selected subset of information items and causes the graphical user interface to display one or more images obtained from the image data included in the selected subset of information items selected using the search criterion so as to represent the content of the selected subset of information items.

Abstract
An information retrieval system in which a set of distinct information items map to respective nodes in an array of nodes by mutual similarity of the information items, so that similar information items map to nodes at similar positions in the array of nodes; the system comprising: a user control for defining a search criterion for selecting information items; a detector for detecting those positions within the array of nodes corresponding to the selected information items; a graphical user interface for displaying a two-dimensional display array of display points representing those positions within the array of nodes corresponding to the selected information items; and a processor responsive to the selected information items, for providing a representation which is generally representative of the information content of the selected information items.

20. An information retrieval method in which a set of distinct information items map to respective nodes in a self-organizing map by mutual similarity of the information items, so that similar information items map to nodes at similar positions in the self-organizing map, wherein the self-organizing map is trained upon reduced dimension characterizations of the information items, the method comprising:
-
defining a search criterion for selecting a subset of the information items represented by the self-organizing map, the search criterion being applied using a standard keyword search technique; detecting those positions within the self-organizing map corresponding to the subset of the information items selected by the standard keyword search technique; displaying display points which are at positions representing only those positions within the self-organizing map corresponding to the selected subset of information items; and in response to the selected subset of information items selected using the search criterion, providing one or more representations representative of the information content of the selected subset of information items, wherein each of the information items represented by the self-organizing map includes image data; and wherein the providing step includes displaying one or more images obtained from the image data included in the selected subset of information items selected using the search criterion so as to represent the content of the selected subset of information items. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A computer-readable medium storing a program that, when executed by a computer, causes the computer to generate a user interface of an information retrieval system in which a set of distinct information items map to respective nodes a self-organizing map by mutual similarity of the information items, so that similar information items map to nodes at similar positions in the self-organizing map, wherein the self-organizing map is trained upon reduced dimension characterizations of the information items, the interface comprising:
-
a user control for defining a search criterion for selecting a subset of the information items represented by the self-organizing map, the search criterion being applied using a standard keyword search technique; and a graphical user interface configured to display points representing only those positions within the self-organizing map corresponding to the subset of information items selected by the standard keyword search technique and to display one or more representations representative of the information content of the subset of information items selected by the search criterion, wherein each of the information items represented by the self-organizing maps includes image data; and wherein the graphical user interface is configured to display one or more images obtained from the image data included in the selected subset of information items selected using the search criterion so as to represent the content of the selected subset of information items. - View Dependent Claims (31, 32, 33, 34, 35)
